Abstract
A direct current electrical switching apparatus includes a first contact in electrical communication with first and third arc runners, a second contact in electrical communication with second and fourth arc runners, a movable contact, a first arc chamber including first arc plates having a first width, a second arc chamber including second arc plates having a greater second width, an operating mechanism, and a magnet assembly cooperating with the arc chambers to establish generally oppositely directed magnetic fields. The magnetic fields cause one of a first arc and a second arc to enter one of the arc chambers depending upon a direction of current flow between the contacts. The electrical switching apparatus is rated for a first magnitude of current flowing from the first contact to the second contact and for a greater second magnitude of opposite second current flowing from the second contact to the first contact.
